Tool for splitting metal nuts



June 26, 1951 R. R. BEEZLEY TOOL FOR SPLITTING METAL NUTS Filed Aug. 4,1947 INVENTOR FEZLE Y Patented June 26, 1951 UNITED STATES PTENT orr cg1 Claim.

This invention relates to devices for splitting nuts which have jammedon the bolt or stud and may not readily be removed therefrom in ordinarymanner, so that their removal may be easily accomplished.

In many places nuts remain on the bolts or studs for quite sometime andbecome so rusted, or otherwise so tightly adhered that an endeavor toremove them by a normal method of unscrewing results in twisting off thebolt or stud, making it necessary in the case of studs to drill out thebroken stud and retap the hole and replace the stud before the parts canagain be put to gether. This being not only normally troublesome andexpensive but often in automobile construction because of crampedconditions, being almost impossible.

The primary object of this invention is to provide a tool for thepurpose of longitudinally splitting nuts whereby their removal from abolt or stud may be readily and easily accomplished.

To provide means which may be operated from a position laterallydisposed from the nut whereby access may be had to nuts in crampedpositions.

To provide a simple, rugged and easily operable tool for splitting nuts.

The means by which the foregoing and other objects are accomplished andthe method of their accomplishment will readily be understood from thefollowing specification on reference to the accompanying drawings inwhich:

Fig. 1 is a side elevation of the tool partially in section along thelongitudinal center line thereof.

Fig. 2 is a corresponding sectional plan taken on the line II--II ofFig. l, with the nut and stud from which the nut is to be removed shownin dash lines.

Fig. 3 is a transverse elevational view taken on the line III-III ofFig. 1.

Referring now to the drawings in which the various parts are indicatedby numerals:

The tool comprises an elongated body Ill, provided with internal threads12 extending from one end along the longitudinal center line of the bodyfor substantially one-half its length. Beyond the center the body is cutaway to form parallel, flat upper and lower surfaces l4 and I6, whichextend to the opposite end. Adjacent that end this flattened portion ischambered out to form a socket [8 for the reception of the nut which isto be split. Extending longitudinally from this socket along the centerline of the body toward the threaded end the flattened portion of thebody is cut out to form a slot 20, adapted to slidably receive arectangular chisel 22 which is of equal depth with the flattened portionof the body. The chisel 22 is slidably confined within the slot by upperand lower plates 24 and 26, at least one of the plates being removablyheld in place by cap screws 28.

Disposed in the threaded end of the body I0, is a set screw 30 foraccomplishing cutting thrust on the chisel 22. A plunger 32 looselycentered by the threads l2 may be interposed between the set screw 30and the chisel 22, the plunger preferably having a pointed and roundedend 32A and the set screw end being correspondingly cupped to effectcentering contact therebetween.

The body I0 may be cylindrical, or of hexagonal or other cross section,but if cylindrical, is preferably shaped adjacent its threaded end IOAfor wrench engagement.

In assembling the tool the plate 22 is removed,

the chisel I2 is placed in the slot 20 and the' plate secured in place,to slidably hold the chisel in the slot, the plunger 32 is insertedthrough the threaded end of the body and the screw 30 engaged andscrewed into place.

In using the tool the socket I8 is engaged over the nut 34 to be split,and the screw 30 run down to engage the plunger 32 against the chisel 22and force the point of the chisel into cutting and splitting engagementwith the nut. This thrusting movement being obviously continued untilsplitting of the nut is accomplished. The set screw 3! is turned by theuse of a suitable wrench and if necessary the body It] is held againstturning as by a wrench 36 engaging the end IDA of the body. Obviously apermanently attached handle corresponding to the wrench 36 may beattached to the body but such construction is not preferred.

It will be distinctly understood that the inter posed plunger 32 may beomitted and the end of the screw directly contact the chisel withoutparting from the spirit of my invention.

It will be further understood that the nut receiving socket istransverse to the axis of the body and the screw and not only holds thenut which is to be split but forms an anvil against which the cuttingaction of the chisel takes place.

I claim:

A tool for splitting metal nuts; said tool comprising an elongatedtubular body having one end portion shaped to polygonal cross-sectionfor engagement and holding against turning as by a wrench, and itsopposite end portion fiattened by cutting away opposite side portions,

' 0 said flattened end portion being chambered transversely to saidsides to form a polygonal nut receiving socket and being slottedsymmetrically with respect to the longitudinal axis of said body awayfrom said socket, said body being internally threaded along saidlongitudinal axis from said slot through said polygonal end, a chisel ofuniform rectangular crosssection slidably disposed in said slot, saidchisel having a centrally disposed cutting edge at one of its ends andbeing transversely flattened at its opposite end, means at least one ofwhich is removably secured respectively to opposite sides of saidflattened end portion of said body adjacent said socket and slidablyconfining said chisel in said slot, and a thrust screw in the threadedend of said body cooperating with said chisel to effect cutting thrustof said chisel against said nut.
